Mary will face Poland's Karolina

The mother-of-two, who is also a multiple-time Asian champion, will face Poland's Karolina Michalczuk -- a former bantamweight (54kg) world champion -- in her pre-quarterfinal bout on Sunday at 1830hrs (IST).

Mary needs to win two bouts to be assured of a medal

The Indian, who was made the face of International Boxing Association's campaign to get women's boxing included in Olympics, needs to win just two bouts to be assured of a medal and first up for her is Michalczuk.

Michalczuk, a 32-year-old, won a bronze medal at the World Championships this year.
